Space Station Commander Provides Tour of Orbital Laboratory

Space Station Commander Provides Tour of Orbital Laboratory

THIS IS AMAZING— Some have no idea as to what the Space Station interior looks like. This is very impressive.  Something worthwhile watching.

Published on Nov 19, 2012 - In her final days as Commander of the International Space Station, Sunita Williams of NASA recorded an extensive tour of the orbital laboratory and downlinked the video on Nov. 18, 2012.  Continue reading

Australia pioneers renewable power – video

Australia pioneers renewable power – video

Published on Apr 12, 2014 - Engineers on a small Australian island are claiming to have perfected renewable energy supply for sustained periods. At times, all of King island is powered by renewable energy, meeting the needs of its 2,000 inhabitants. Despite using diesel, it is hoped it will make renewable energy a viable option for other small communities around the world. ….Al Jazeera’s Andrew Thomas reports from King island, Australia.

Half-century milestone for IBM mainframes

Half-century milestone for IBM mainframes

IBM S360 mainframeMainframes were the workhorses of business for many years
The IBM mainframe is celebrating its 50th anniversary.  The first System 360 mainframe was unveiled on 7 April 1964 and its arrival marked a break with all general purpose computers that came before.

The machines made it possible to upgrade the processors but still keep using the same code and peripherals from earlier models. Later this year the British rival to IBM’s machine, the ICL 1900, also celebrates its 50th anniversary. Despite their age, mainframes are still in wide use now, said Barry Heptonstall, a spokesman for IBM.  “I don’t think people realise how often during the day they interact with a mainframe,” he said.  Continue reading

Five Signs Solar Power is Taking Over the World – video

Five Signs Solar Power is Taking Over the World

solar panelsThis post originally ran on Juan Cole’s Web page.

Burning fossil fuels (coal, natural gas and oil) is putting 32 billion metric tons of carbon dioxide annually into the atmosphere. Since CO2 is a greenhouse gas that traps heat from the sun on earth and prevents it radiating back out to space, this unprecedented human output is causing climate disruption, a process that will accelerate over the next few decades and will prove extremely costly to human society (if the latter can even survive).

The only energy source that has a hope of fixing this problem and of resolving the coming energy crisis is solar.  The cost of solar panels is falling rapidly, raising the hope that we can put in enough panels quickly enough to avoid the very worst scenario of carbon-induced climate disruption.  (I put in 16 Enphase microinverter panels at my place this winter and they generated 120 kilowatt hours in the past week; my house and electric car averaged 150 kilowatt hours usage per week last month; and that is in Michigan at the tail end of winter).

Buckminster Fuller’s Geodesic Dome home is now a museum

Buckminster Fuller’s Revolutionary Geodesic Dome Home to be Transformed into a Museum


Buckminster Fulle Dome Restoration

  By Christina Sarich

“Everything you’ve learned in school as “obvious” becomes less and less obvious as you begin to study the universe. For example, there are no solids in the universe. There’s not even a suggestion of a solid. There are no absolute continuums. There are no surfaces. There are no straight lines.” ― Buckminster Fuller

It was the world’s first geodesic dome, imagined and made real by one of the most revolutionary minds of our time. The home was built in the 1960s and was inhabited by the designer and his wife before his passing, but it is still an inspiring monument to a philosopher and architect like no other, R. Buckminster Fuller. Fortunately, it will be made into a museum, free to the public in April of this year, due to a recent investment by inspired individuals.

Concerns about Hydro projects in the Mazaruni District

Hi Cyril,

You might have seen the press coming out of Guyana today that the government is going ahead, with the help of Brazil. with a US$45M study for the development of hydro power in the Upper and Middle Mazaruni Regions in Essequibo.
e.g. see Alva Solomon’s story in Demerara Waves:

US$45M to study Mazaruni hydropower potential

The government officials went to a few Amerindian settlements over the last week and told them that two schemes will be developed – one in the Upper Mazaruni and another in the Middle Mazaruni, and that their villages and land will not be flooded as the new technology reduces the size of reservoirs by 90%. Apparently they feel that that was enough ‘consultation’ necessary to satisfy international requirements of ‘free, prior and informed consent’.

There are very few reports available in the public domain. Survival International had done some research around the Amaila Falls Hydro and had looked at all information gleaned about possible Mazaruni Potaro hydro that may affect the Akawaio, Patamona and Arecuna people.  (see FOREWORD and PDF link to this report below)

I don’t know if there are any lawyers, environmentalists or hydro-power engineers in the Diaspora who may want to weigh in and give the residents and all citizens of Guyana some advice.

USDA to Spend $3 Million to Save Honeybees

USDA to Spend $3 Million to Save Honeybees

By Christina Sarich

Article imageFinally the USDA will do something right for a change. Just this week, the U.S. Department of Agriculture pronounced it would spend $3 million to help the nations honeybees in the Upper Midwest as an act to reverse the damage to bees and colony collapse disorder – linked largely to he abundant use of neonicotinoids and glyphosate.

Honeybees pollinate an estimated $15 billion in crops every year. Many beekeepers bring their hives to the MidWest during the summer so that they can gather nectar and pollen for food, and then truck them to California to pollinate diverse crops from kiwi to rambutan, apples, alfala and pomegranates.   Continue reading

The Internet could crash. We need a Plan B – Danny Hillis

Danny Hillis: The Internet could crash. We need a Plan B

Published on Mar 18, 2013 – TED talk

In the 1970s and 1980s, a generous spirit suffused the internet, whose users were few and far between. But today, the net is ubiquitous, connecting billions of people, machines and essential pieces of infrastructure — leaving us vulnerable to cyber-attack or meltdown. Internet pioneer Danny Hillis argues that the Internet wasn’t designed for this kind of scale, and sounds a clarion call for us to develop a Plan B: a parallel system to fall back on should — or when — the Internet crashes.

List of African-American inventors and scientists – Wikipedia


List of African-American inventors and scientists

From Wikipedia, the free encyclopedia

This list of African-American inventors and scientists attempts to document many of the African Americans who have invented a multitude of items or made discoveries in the course of their lives. These have ranged from practical everyday devices to applications and scientific discoveries in diverse fields, including physics, biology, mathematics, plus the medical, nuclear and space sciences.

Among the earliest was George Washington Carver, whose reputation was based on his research into and promotion of alternative crops to cotton, which aided in nutrition for farm families. He wanted poor farmers to grow alternative crops both as a source of their own food and as a source of other products to improve their quality of life. The most popular of his 44 practical bulletins for farmers contained 105 food recipes using peanuts.[1] He also developed and promoted about 100 products made from peanuts that were useful for the house and farm.[citation needed] He received numerous honors for his work, including the Spingarn Medal of the NAACPContinue reading

The Good Old Days – not so long ago!

The Good Old Days – not so long ago!

Iowa, USA 2014: One evening,  a 17 year-old- grandson was talking to his grandmother about current events. The grandson asked his grandmother what she thought about the shootings at schools, the computer age, the Internet and just things in general in this “modern age”….

The Grandmother replied, “Well, let me think a minute, I was born before:
‘television, penicillin, polio shots, frozen foods, Xerox, contact lenses, Frisbees and the pill
There were no: credit cards, laser beams or ball-point pens
Man had not yet invented: pantyhose, air conditioners, dishwashers, clothes dryers, and the clothes were hung out to dry in the fresh air and man hadn’t yet walked on the moon.  Continue reading
